Inventor: SOGA GEORGE
IPC: G01G15/02
Filed: 1977-08-19
Granted: 1979-11-27
Abstract: ABSTRACT OF THE DISCLOSURE           The invention relates to a material portioning appara-tus and a method which provides portions of material of predeter-mined weight by measuring and portioning an appropriate volume of the material.  Although the apparatus is especially useful when the material consists of whole pieces larger than the por-tioned sizes, such as fillets of fish or meat, it can also be used for portioning granular materials, or materials of sizes smaller than the portioned sizes.  It is only necessary that the material, or bulks of the material, be of such a nature that, when it is compressed in one direction, it will expand or be forced to move in a different direction.  In accordance with the invention, the apparatus comprises a preforming stage having an adjustable volume, and a weighing stage also having an adjustable volume.  Material is fed, through the preforming stage, into the weighing stage and the weighing stage is overfilled to include a volume greater than the desired weight.  The volume of the weighing stage is then adjusted to the desired volume, and any excess material will be forced back into the preforming stage.          A separating means is then inserted between the weighing stage and the preforming stage to separate the materials in the two stages, and the amount remaining in the weighing stage is the amount, required by weight, of material.

Abstract: ABSTRACT OF THE DISCLOSURE:       A method and apparatus for locating a work member supporting fixture on a table and for clamping the fixture in located posi-tion on the table, especially to locate and clamp the work member during machining, in which the table is fixedly mounted in place, for example, in a machine tool with an upwardly facing horizontal surfaced receivable on the upper surface of the table and is adap-ted for fixedly supporting a work member therein.  The table has passages therein under fluid pressure and a plurality of outlets lead from the passages through the upper surface of the table and are preferably provided with normally closed valves adapted to be actuated into open position by movement of a fixture there-over.  The passages and outlets provide means for establishing a fluid film under pressure between the downwardly facing sur-face of the fixture and the  upwardly facing surface of the table so that the fixture floats on the film and can be moved about easily on the table. Cooperating elements of pin and socket locating devices on the fixture and table provide for the loca-tion of the fixture in predetermined positions on the table and clamps are provided to clamp the fixture in located positions on the table.  The locating devices on the table bear a pre-determined relation to the work axis of the machine tool, a spindle axis, for example, and can, therefore, be depended on to locate the fixture in predetermined accurate positions for machining.  A work member located in the fixture can, thus, be positioned rapidly for the machining of various regions thereof.

Abstract: INSTRUMENT FOR RECORDING BLOOD PRESSURE                   ABSTRACT OF THE DISCLOSURE The electronic sphygmo-manometer is based on a sleeve, which is wound around the patient's arm for taking pulse pressure values.  The sleeve is equipped with a sound transducer connected to the pressure gauge.  The point of the pressure gauge is deflectable perpendicular to the rotation plane and the needle tip can be brought into contact with a record card beneath the needle by means of an electro magnet.  If the electro magnet is activated by a power circuit, which is controlled by an electrical signal created from the Korotkoff noise, the needle tip is pressed against the record card and produces an imprint on the record card.  By sweeping the pressure from a value above the systolic pressure to a value below the diastolic pressure, a card is obtained with imprints covering the pressure range from the systolic to the diastolic value.  The instrument is easily to be operated and provides for a high accuracy combined with low suscep-tibility to noise.

Abstract: S P E C I F I C A T I O N     FOLDABLE CURLING IRON PROVIDING FOR SELF-STORAGE AND SAFETY DISCONNECTION     Inventor:  Patrick M. Tomaro ABSTRACT OF THE DISCLOSURE     A curling iron includes a tubular barrel containing an electric heating element and extending from a handle, and a hair-holding clamp conforming to the surface of the barrel.  The clamp may pivot with respect to the barrel by means of a spring biased lever.  The barrel and clamp pivot together about a pin in the handle extending transverse to the barrel so that the barrel and clamp may be pivoted about 180 degrees from its extended position into a folded position within the handle.  As the barrel pivots from its extended position, two contacts mounted on a drum, which pivots with the barrel, move out of contact with spring contact elements fixed to the handle, thereby electrically disconnecting the heating element from its electric source.         The handle includes a spring biased clamp   As the barrel and clamp are folded into the handle, the doors are pushed inwardly out of the way so that the handle may receive the barrel and clamp for storage.  When the barrel is in the extended, oper-ative position, an abutment member on the drum presses against the inner surface of the handle doors, thereby firmly retaining those doors in their outward, closed position.

Abstract: WELL LOGGING METHOD AND APPARATUS   USING FRICTION-REDUCING AGENTS            Abstract of the Disclosure.  A well logging instrument has a fluid chamber at its lower end and a plurality of controlled flow orifices leading from the chamber to the exterior of the instrument.  A piston within the chamber, having a spring at its upper end, forces a friction-reduction agent from the chamber through the flow-controlled orifices into the earth borehole to facilitate the movement of the well logging instrument through the borehole.  The upper portion of the fluid chamber, above the piston, is also ported to the fluid within the borehole to equalize the pressure across the piston.  In an alternative embodiment of the invention, the acceleration of the borehole instrument creates a velocity signal which is compared with the velocity of the logging cable at the earth's surface and upon a sufficient difference in velocity, the friction-reduction agent is caused to be ported into the earth borehole.

Abstract: ABSTRACT OF THE DISCLOSURE          A chopper and a series circuit of a dynamic braking resistor and a thyristor are connected in parallel with a d.c. motor which is operated as a generator during braking operation. A series circuit of a diode and an inductance element is connected in series with the d.c. motor.  A condenser connected between the ground and the junction of the inductance element and the diode forms a filter circuit together with the inductance element.          Current generated by the d.c. motor flows into a d.c. source through the diode and the inductance element during regenerative braking operation.  An over-voltage detector fires the braking thyristor when the voltage across the condenser becomes greater than a predetermined limit value, as a result the dynamic braking operation is performed.          A chopper controller varies the interval between an ON pulse to turn the chopper into ON state and an OFF pulse to turn the chopper into OFF state for adjust-ing ON time and OFF time of the chopper in response to the current through the d.c. motor.  An operation changer provides a signal to an automatic phase shifter to extend the interval between the ON and OFF pulses to a predeter-mined period of time enough to quench the braking thyristor when the braking operation of said d.c. motor is changed from the dynamic braking operation to the regenerative braking operation.

Abstract: BLOOD COLLECTION SYSTEM WITH VENIPUNCTURE               INDICATOR     ABSTRACT OF THE DISCLOSURE         A blood sample collection system including an indicator for denoting successful venipuncture prior to entry into an evacuated tube portion of the system.  The system includes a double ended cannula open at both ends and having a passageway therethrough.  A holder is provided for mounting the cannula thereon-with one end extending forwardly and adapted for veni-puncture and the other end extending rearwardly and being adapted for coupling with a sample collection container.  The evacuated sample collection container has a closed end and an open end with the open end closed by a self-sealing puncturable stopper.  The stopper is adapted to be penetrated by the rear end of the cannula to provide fluid communication between the passageway through the cannula and the interior of the sample collection container.   A pressure responsive indicator is on the stoppered collection container and is adapted to physically deform when the one end of the cannula is introduced into the vein and the other end of the cannula is introduced a predetermined distance into the stopper.  The deformation is sufficient to permit a small amount of blood to enter the cannula for visual observation of a successful venipuncture.  Indexing structure is on the holder and stoppered container to facilitate relative positioning of the stopper and cannula end penetrating therethrough in at least one position to facilitate venipuncture and operation of the pressure responsive indicator.

Abstract: SAMPLE DATA POSITIONING SYSTEM EMPLOYING A MODEL OF THE    PHYSICAL SYSTEM FOR TIME OPTICAL CONTROL          Abstract of the Disclosure A sampled data positioning system for moving a member between positions in a minimum time employs a model of the physical system to overcome the low bandwidth constraints of fed back position and velocity samples.  The model system is an approximate analog of the physical system and provides continuous pseudo position and velocity signals of high bandwidth.  These are applied to a seek controller which generates an error signal between a desired reference velocity trajectory and the pseudo velocity signal.  The error signal is fed back to the model system input and is also applied to control the physical system.  The model velocity and position outputs are reset at sampling times to the values of the sampled velocity and position in the physical system.
